"The Campaign" star Zach Galifianakis is reportedly gearing up to wed Quinn Lundberg this weekend in Vancouver, British Columbia.

The 42-year-old actor, known for films such as "The Hangover" and "Due Date," has not confirmed that his wedding will take place this weekend. However, in June, a wedding invite was leaked to the press listing August 11 as the big day.

The couple reportedly hosted their wedding rehearsal dinner at the Tea House at Stanley Park in Vancouver, BC on August 9. The venue's Twitter account teased followers with a photo of the dining room and the caption, "Beautiful day for a wedding rehearsal dinner."

Lundberg is the vice president and co-founder of the non-profit organization Growing Voices, which connects international donors with community-based projects, according to the group's official website. The 29-year-old is a trained dancer and manages Growing Voices from their Brooklyn, New York headquarters.

Galifianakis has actively supported the charity, which also works to help survivors of domestic violence.

According to Celebuzz, Galifianakis and Lundberg's wedding registry included a sheet set from Anthropologie and asked guests to donate to Growing Voices.

Galifianakis currently stars opposite Will Ferrell in this week's release of "The Campaign," which earned $10.3 million in Friday's box office.

Galifianakis is known for his stand-up comedy career and his roles in films like "The Hangover," "Puss in Boots" and "Dinner for Schmucks."
